Little Big Town Perform 'Pontoon' On Good Morning America

Little Big Town stopped by Good Morning America to boost awareness of their recently released album, Tornado, and to play their hot single "Pontoon."

"Pontoon," has already gone platinum and is the first single from LBT to hit number one.

"Nobody tells us when we quit. We say when we're done," said Karen Fairchild, recalling some of the band's harder times. "When we look at each other in the eye and we say, 'Let's not do this anymore,' then we'll stop. But no one else gets to tell us that. No label. No publisher. No anybody."

Little Big Town is currently on the road with Rascal Flatts for the latter's Changed tour. The band hits Chula Vista, California's Cricket Wireless Amphitheatre on September 15.
